摘要:
研发了一套室内试验装置及方法,通过设置倾角将竖向载荷分解为垂直或平行于试件表面的分力,实现对刚柔复合式路面结构的室内压剪试验.采用Abaqus软件分析了复合试件的三维应力分布,通过室内试验对比了不同试验方法的强度值,测试了不同因素对压剪强度的影响,并拟合出考虑温度和沥青层厚度的压剪强度模型.有限元分析结果表明,试验采用的压头和试件组合能较好地模拟实际路面结构的应力分布状态.试验结果表明,温度和沥青层厚度是影响复合式试件压剪强度值的主要因素.当试件压剪破坏时,对应的层间剪应力恒小于层间剪切强度,若荷载扩散角为45°,则层间剪应力仅为层间剪切强度的8%,从而确定了复合试件的破坏位置在沥青面层而非层间处.
Abstract:
A set of laboratory load device and test method was developed. The vertical load was decomposed into the perpendicular or parallel forces to the surface of the specimen by setting dips to realize the laboratory compressive-shear tests for rigid-flexible composite pavement structure. The three-dimensional stress distribution of the composite specimen was analyzed by Abaqus software. The strength values of different test methods were compared by indoor experiments, and the effects of different factors on the compressive-shear strength were tested. The compressive-shear strength model considering the temperature and the asphalt layer thickness was fitted. The finite element analysis results show that the combination of the indenter and specimen can simulate the stress distribution of the actual pavement structure. The test results show that the temperature and the asphalt layer thickness are the main factors affecting the compressive-shear strength of the composite specimens. When the specimen is destroyed by the compressive-shear stress, the corresponding interlaminar shear stress is constantly less than the interlaminar shear strength.When the load diffusion angle is 45°, the interlaminar shear stress is only 8% of the interlaminar shear strength, showing that the failure position of the composite specimen is in the asphalt surface layer instead of the interlamination.
